Why is there no horizontal approval for nave wood carving pendant?

1. First of all, nave, a big family in ancient times, has paintings, with couplets on both sides, and there is no comment on them. The content varies with the status and temperament of the owner.

2. Secondly, from the aesthetic point of view, nave's paintings and woodcarving pendants are mainly dignified and heavy, and adding couplets on both sides will be more elegant and generous. If you add horizontal criticism, it will destroy this aesthetic feeling and look neither fish nor fowl.
